instrument lights

[USA64]

I have opened my tach and speedometer because of a powder being on the inside of the glass. The powder proved to be the reflective paint on the inside of the housing which casts an indirect light on the face. I thought it might be of use to the less intrepid/foolish who do not open the works to see what was inside. In particular note that the light bulbs insert into a tube which approaches but does not connect to the lens. The final connection is made by a short length of white, rubber, tube which fits into the socket tube and over the lens back. I found one intact, petrified tube on the ignition lens, and one perished, broken tube on the high-beam lens. The ignition lens was completely covered on the inside so no light could get through. I wonder how much cursing of the electrics might have ensued when the light stubbornly refused to work after I had replaced the entire harness?

This is helpful, many thanks.

I've become a bit of a fan of Serge Sleurs' restoration of his Europa, as shown in his many YouTube videos. One deals with the speedo & tacho. May be of interest to others...

To add further, it seems that the inside is galvanized. This results in the paint (Rustoleum self-priming spray can) not adhering well. I think if I do it over, and I may, I will use a water-based primer (Zinzer Bullseye) first.

If the can is galvanized steel, try muratic acid (usually used in ceramic tile cleaners) to etch the galvanizing, neutralize with baking soda and then prime for paint.

I sand blasted mine, no trouble with paint adherance after that
